Answer:
Because genetic drift (Founder effect) is acting on this population. Not all the Hardy weinberg criteria are accomplished. There are no random matings and populations are finite-sized.
Explanation:
This is a special case of genetic drift: the founder effect.
The “Founder effect” phenomenon refers to cases where a new population originates from a few founder individuals, coming from a bigger ancestral population, that established in a new environment. This small population might or might not be genetically representative of the original one. This subgroup carries with them some genetic information that they share with their original population. Over time, some genes can be lost, or they can increase in frequency. Some rare alleles might be exceeded or might be completely lost. On Consequence, when the small population grows, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced and enhances the possibility of developing a peculiar allelic composition. In some cases, the founder effect is part of the process of speciation.
The criteria for maintaining a Hardy-Weinberg equilibrium are:
- Random matings
- No superposed generations
- No mutations
- No migration
- Infinite population size
- No natural selection
Genetic drift involved the un-accomplishment of random matings and infinite population sizes.
Genetic drift involves:
- limited population sizes
- individuals reproduce by endogamy/exogamy, and matings occur by phenotype.
Answer:
Belief perseverance
Explanation:
Belief perseverance can also be referred to as belief persistence; it is the tendency for an individual to hold to his/her own initial belief in something despite receiving a new information that debunks the basis of one's initial belief. An individual prefers to discredit the new belief despite sufficient evidence to discredit one's initial belief, just because they misinterpret or totally see no significance on the new information that was received.
Rachael's thinking of fast foods of being harmless, despite the information that fast foods are harmful is called belief perseverance.
Instructions from characteristics which are passed from the
parent to the offspring are called genes. Genes are made of complex molecules
of DNA. Each parent also donates chromosomes to their offspring. Each offspring
will get half of their genes from each parent and they will therefore have the aspect
of the two parents.
